    Re: Post a picture of what's on your bench?

    The mandolin did clean up nicely and the bug excrement all came off without leaving any staining or blemishes. Still have some poo spots inside and I may yet go after those with a bit of dampened rag...

    Re: Hide glue question

    My shop is too thermally transparent to heat my work turning up the thermostat. Infra Red lamps solve that problem and as John has mentioned, using the glue a bit on the thin side with hot lamps, way...

    Re: Post a picture of what's on your bench?

    The F2 you did turned out very nicely. Looks like it closed up quite well at the back of the neck, you can hardly see the break, my project was missing a bit more wood. I opted for a thicker head...

    John, I have been using carbon fiber as reinforcement for other applications and it just occurred to me that this head stock repair would be a perfect application. I had not previously seen or heard...

    Yes, it was rather time consuming. Ended up pretty close to 14 hrs of work, start to finished with a new set up. It was totally a worthwhile save though. The mandolin is otherwise...

  11. Re: Cleaning up after an outgassed celluloid pickguard

    I use Bronze wool instead of steel wool. You still need to take care around any open electronics though, Bronze is conductive but it won't stick to anything magnetic. Pretty good at cleaning up a...

    Re: K1 Mandocello... factory spliced neck?

    The new looking cross grain Spruce in there is new, or at least recent. It is obvious that the back has been off at some point not too long ago, I suspect the current owner bought that way. I have it...

    Re: K1 Mandocello... factory spliced neck?

    If nothing else, it would be a good excuse to replace the black light I don't have anymore. Thanks for suggesting this.

    Re: K1 Mandocello... factory spliced neck?

    OK, more images. The head stock is not involved with the spliced wood but does look correct to me.

    Re: K1 Mandocello... factory spliced neck?
